You can check your Node.js version by typing `node -v` in the Terminal prompt.

+The easiest way to get started is by running the Local Environment setup script, `./bin/setup-local-env.sh`. This will check if you have everything installed and updated, and help you download any extra tools you need.

 You should also have the latest release of <a href="https://npmjs.org">npm installed</a>, npm is a separate project from Node.js and is updated frequently. If you've just installed Node.js which includes a version of npm within the installation you most likely will need to also update your npm install. To update npm, type this into your terminal: `npm install npm@latest -g`

 First, you need a WordPress Environment to run the plugin on. The quickest way to get up and running is to use the provided docker setup. Just install [docker](https://www.docker.com/) on your machine and run `./bin/setup-local-env.sh`.
 
 The WordPress installation should be available at `http://localhost:8888` (username: `admin`, password: `password`).

+Inside the "docker" directory, you can use any docker command to interact with your containers. If this port is in use, you can override it in your `docker-compose.override.yml` file. If you're running [e2e tests](https://wordpress.org/gutenberg/handbook/reference/testing-overview/#end-to-end-testing), this change will be used correctly.
 
 Alternatively, you can use your own local WordPress environment and clone this repository right into your `wp-content/plugins` directory.

This ensures that we are consistent with WordPress PHP coding standards.
 
-When making any changes to the PHP code in this project, it's recommended to install and run `phpcs` on your computer.  This is a step in our Travis CI build as well, but it is better to catch errors locally.
+The easiest way to use PHPCS is [local environment](https://github.com/WordPress/gutenberg/blob/master/CONTRIBUTING.md#local-environment). Once that's installed, you can check your PHP by running `npm run lint-php`.
